Claims13
A method of manufacturing a crystalline magnesium alloy plate, comprising the steps of:
- melting raw materials into liquid metal, wherein the liquid metal contains no solids;
- molding the liquid metal using a movable mold with a continuous mold structure;
- casting at a casting rate of 0.5 meters/minute or more;
- and
- cooling the liquid metal into the crystalline magnesium alloy plate;
- wherein the thickness of the crystalline magnesium alloy plate is not less than 1 mm, and not more than 60 mm, and the width of the plate is larger than the thickness of the plate, and
- the cooling step has a cooling rate of at least 50 degrees Celsius per second, and not more than 100 degrees Celsius per second.
